further, we will get to the truth. thank you very much indeed, congressman. i appreciate it. >> thanks, piers. appreciate your time. now to the first and only vice presidential debate. tens of millions of americans watched the debate last night, among them the vice president's son, beau biden, who joins me now. my immediate question to you is, does your dad do that scary laugh to his own kids? >> look, my dad's a wonderful, wonderful father. i tell folks if i'm half as good a dad to my two kids as he' been to my and my brother and sister, i'm in good shape. he's as fun and serious as you saw him last night. he's as engaged. he finished that debate last night, got on a plane, went home to wilmington, delaware, got up this morning and went to grandparents day. he's a wonderful dad. >> i watched it last night, like over 50 million american viewers over here, and i thought that he nailed it. i thought he won quite comfortably. were you surprised that a lot of the polls had it as a tie? did you feel in the moment that your dad had won quite easily?
